KA
Cloud Support Engineer at a tech vendor with 10,001+ employees
Focused on reworking interface and ecosystem while load balancing has improved uptime
A10 Networks Thunder ADC is quite solid, but there are some issues that I face, particularly with the user interface. A current issue is that the GUI is less polished than competitors. When compared against F5 BIG-IP or Citrix ADC, the GUI is not as good. The documentation and learning curve are areas that can be improved by A10 Networks. Compared with larger vendors including F5, Cisco, or Palo Alto, A10 has a smaller ecosystem. Although A10 Networks Thunder ADC supports cloud and Kubernetes, many enterprises now expect deeper cloud-native functionality. Improvement areas include Kubernetes Ingress maturity, service mesh integration, and auto-scaling intelligence.
